Denoising an image by denoising its curvature image

M Bertalmio, S Levine - SIAM Journal on Imaging Sciences, 2014 - SIAM
In this article we argue that when an image is corrupted by additive noise, its curvature
image is less affected by it; ie, the peak signal-to-noise ratio of the curvature image is larger …

Generating structured nonsmooth priors and associated primal-dual methods
